#申请开发板# #申请原创# 很荣幸收到极海赠送的APM32E030开发板，今天来测试一下跑分性能。首先从github上下载coremark源代码库
coremark
我只需要其中这几个文件，把它们放在一个文件夹里
然后添加到KEIL工程里面
开始修改
1.首先修改启动文件的堆栈空间，设大一些
2.修改portme文件
//#define NSECS_PER_SEC CLOCKS_PER_SEC
//#define CORETIMETYPE clock_t
//#define GETMYTIME(_t) (*_t = clock())
#include "hal_systick.h"
#define NSECS_PER_SEC TICKS_PER_SECOND
#define CORETIMETYPE uint32_t
#define GETMYTIME(_t) (*_t = hal_systick_get())
#define MYTIMEDIFF(fin, ini) ((fin) - (ini))
#define TIMER_RES_DIVIDER 1
#define SAMPLE_TIME_IMPLEMENTATION 1
#define EE_TICKS_PER_SEC (NSECS_PER_SEC / TIMER_RES_DIVIDER)
/** Define Host specific (POSIX), or target specific global time variables. */
static CORETIMETYPE start_time_val, stop_time_val;

#endif
#endif
#ifndef COMPILER_FLAGS
#define COMPILER_FLAGS "-Omax" /* "Please put compiler flags here (e.g. -o3)" */
#endif
#ifndef MEM_LOCATION
#define MEM_LOCATION "STACK"
#endif
#define ITERATIONS 10000 // 这个值需要保证能够运行至少10秒，可以先写一个值，运行不足10秒会报错，再回来修改
#if MAIN_HAS_NOARGC
MAIN_RETURN_TYPE
coremark_main(void)
{
int argc = 0;
char *argv[1];
#else
MAIN_RETURN_TYPE
coremark_main(int argc, char *argv[])
主函数添加核心功能函数

编译后烧录代码
打开串口助手，115200波特率
等待10S左右时间会出现跑分结果
可以看到，APM32E030 EVAL评估板 coremark跑分:
153.699548 分，在开最大优化等级 -Omax条件下
这个分数在Cortex M0中很强了
